Description
Technical field
The present invention relates to a kind of ultrasonic tool.More specifically, the present invention relates to a kind of ultrasound wave cutting blade.Described blade is useful especially in the operation application of cutting as the tissue such as cartilage and bone.The present invention also part relates to relevant operation method.
Background technology
In art of orthopedic surgery, be the prerequisite of many processes to the cutting of active bone.Such process comprise rebuild accidental injury organizational structure, by the bone collection of health to the position damaged because of disease or correct as congenital deformity of face such as mandibular retrusions.Since several century, these tasks are all by using the equipment being referred to as bone saw to carry out.
Conventional bone saw is divided into several fundamental type.Manual saw or brill are exactly require that operator are to be similar to the handheld device of the mode mobile device using wood working tool.No matter power-equipment, be electronic or pneumatic, be reciprocating or revolving.Reciprocating equipment uses flat sword shape blade, wherein moves back and forth provide non-manual by motor.Rotary equipment uses electric rotating machine to carry out rotary drilling-head or has to be similar to table saw blade like that around the blade of the sawtooth of its circumference setting.Now, the conventional bone saw of all these is worldwide for medical procedure.
Although the bone saw of routine possesses functional, it has many shortcomings.Such as, band saw or reciprocating-type saw is utilized all to be not easy to start and to guide cutting.Cutting or must must use starter hole from edge.In order to form starter hole, operation is bored or analogous instrument is holed in bone.Subsequently, cutting blade is inserted in the hole of having bored.Then user just can cut.Alternately, rotary blade can be used.But, when using rotary blade, must carry out along relatively straight path cutting to prevent blade to be stuck in otch.All blades form the restriction that the function to incision bending or have compound angle all greatly can be subject to selected blade.Relatively thick blade saw kerf is wider, makes active bone in cutting process, lose very heavy thickness.Must carry out in the process of rebuilding at great majority, doctor can wish that this width is narrow as far as possible.
The most important thing is, be coupled with the linear of the conventional bone saw sheet carrying out cutting necessary sawtooth or tangential velocity relatively slow, cause frictional wear high, it shows as heat.If bone temperature reaches 47 DEG C exceed the several seconds, heat will cause tissue necrosis.When tissue necrosis, due to the bone undue growth of necrosis, the Post operation influential point of bone bounces back.In this natural postoperative tissue development process, in fact the otch thickness in bone can increase.Bone retraction process must complete before healing can start.In order to prevent the contraction in length of bone, use metallic plate and screw by fixing for GUSUIPIAN middle place in position.These all factors obviously will cause the operating time to increase, and the more important thing is, healing time will be caused significantly to increase, and engage this is because bone must cross over larger span.Some study display, and the intensity of bone also affects adversely.
When upper jaw bone or mandibular bone will be cut in choosing date for operation, the heat effect of conventional bone saw will need more unconventional intervention in case stop loss wound.If damaged bone or do not heal very soon, the jawbone between cutting teeth will cause loss of tooth.In order to prevent loss of tooth, must in the preoperative tooth be separated; Require sometimes patient in the preoperative support with tooth reach 6 months.In these cases, the discomfort of cost and patient significantly increases.
Rise to attempt to reduce necrosis to limit tissue temperature, the operation bone saw of some routines provides liquid coolant to operative site.Such as, see the United States Patent (USP) NO.4 authorizing the people such as Brinckmann, 008,720.Coolant is introduced in the space between each section on cut edge by these equipment usually, or relies on spray method fluid perfusion cutting part.Clinician adopt another kind of technology be form very shallow otch, and increase instrument walk between time.The additional flushing to region, bone temperature rising appropriateness reduces.Certainly, this technology adds the degree of fatigue of operating time and clinician.
Some researcheres have proposed to use ultrasonic tool for osteodiastasis.It is well-known for using ultrasonic operation instrument to carry out cutting through Various Tissues.Although these equipment such as reducing saw kerf size, reduce noise etc. several in be better than conventional bone saw, and can form the otch of complex geometric shapes, but the temperature rising caused due to the frictional heating at blade/place of organizational interface remains a significant problem.Compared with conventional reciprocating bone saw, owing to using ultrasound wave to relate to quick movement, therefore this problem super is more serious.Some designers have managed to reduce heating by carrying out improvement to the cross section of cutting blade.Authorize the United States Patent (USP) NO.5 of Idernoto, 188,102, authorize the United States Patent (USP) NO.4 of Loschilov, 188,952 and authorize the United States Patent (USP) NO.5 of Hood, 261,922 all illustrate the cutting design that pair cross-section carries out improving to reduce frictional heating.
Several ultrasonic equipment provides cooling to cutting blade, and achieves success in various degree.Authorize the United States Patent (USP) NO.4 of the people such as Alperovich, 823,790 designs showing the scalpel blade cooled at low temperatures.But this design in fact may due to freezing and damagine activity tissue.In addition, this design can not provide any coolant to the surrounding tissue directly do not contacted with blade.
Authorize the United States Patent (USP) NO.5 of Idernoto, 205,817,5,188,102 and 4,832,683 all illustrate the example providing fluid-cooled ultrasonic instrument.But, these instruments or best coolant can not be provided in required place (mainly at the cutting part of blade), otherwise for providing the instrument of coolant at most advanced and sophisticated place, the hole for coolant has blocked cut edge.Interrupt, uneven cut edge hinders and operates and make to be difficult to guiding blade on bone surface.
A kind of phenomenon hindering the ultrasonic tool operation of the beneficial effect of surgical site irrigation relevant to its effect is ultrasonic atomization.When making ultrasound wave pendulum and fluid contact, fluid is broken down into droplet, and its size and frequency of vibration are inversely proportional to.In other words, frequency is higher, the less and more movability of drop.The size being vibrated the drop formed by ultrasound wave can be very little, and some diameter is less than 1 micron.This phenomenon is well known in the art.In fact, the much equipment (such as, Wetting apparatus for room, medical spray gun and industrial nozzle) for making the liquid atomization is all based on this principle.And in situations in the surgery room, because spraying granule may comprise virus or bacteria preparation, therefore do not wish that these granules exist.In addition, some fluids just can be atomized before arrival operative site, reduced cooling effectiveness.This just needs a kind of effective means guaranteeing Liquid transfer.
United States Patent (USP) NO.6,379,371 disclose a kind of ultrasonic operation blade with cooling, it has vane body and shank, vane body has level and smooth continuous print cut edge, and one end of shank is connected to vane body, and its opposite end can may be operably coupled to ultrasonic vibration source.Shank is provided with axial elongated hole, and for cooling fluid is delivered to cut edge, simultaneously vane body is provided with the axis be at one end communicated with this hole and extends groove.Vane body is preferably provided with in one end relative with shank and the groove for being communicated with from groove to the hole of cut edge distributing fluids.Described groove can have the structure parallel at least partially with cut edge.Such as, be circular in cut edge, and vane body has when fluid distributes the plane surface between guiding surface and cut edge, groove has to tilt and the fluid distribution surface extended along circular arc relative to plane blade surface.
